    Gem files will remain installed in /home/Dmitry.Veremchuk/.rvm/gems/ruby-1.9.3-p194/gems/ffi-1.0.11 for inspection.
    Results logged to /home/Dmitry.Veremchuk/.rvm/gems/ruby-1.9.3-p194/gems/ffi-1.0.11/ext/ffi_c/gem_make.out
    An error occured while installing ffi (1.0.11), and Bundler cannot continue.
    Make sure that `gem install ffi -v '1.0.11'` succeeds before bundling.

FFI gem is not required in my Gemfile. Though I suppose Capybara requires it. I have the following configuration:
PC with Windows XP and Cygwin (with devtools installed);
Ruby version 1.9.3p194 (in RVM);
Rails version 3.2.8.

I tried to install ffi-1.0.11 separately but sadly with the same result.

Would appreciate any help.
